Imaging of single barium atoms in a second matrix site in solid xenon for barium tagging in a Xe double beta decay experiment
M. Yvaine, D. Fairbank, J. Soderstrom +134
Neutrinoless double beta decay is one of the most sensitive probes for new physics beyond the Standard Model of particle physics. One of the isotopes under investigation is $^{136}…
